RTV 1100 Turbo

[joeshmoe_44883]

Hi everyone, owned my RTV for a year now and as the title suggests, gonna turbo it. I didnt know they made a turbo kit untill i got on here and did some searching, pretty neat. I'm gonna go one step further and add an intercooler to the setup, along with straight piping it to an exhaust stack i got from a CAT D4 dozer. The head is getting pulled off, o-ringed, ported an polished, and adding head studs to make sure the head stays clamped down tight. If anyone is interested i'll post up some pictures as I go through the build in case anyone wants to do the same to thiers. Maybe if enough people do it we'll be able to convince Kubota to start producing Turbocharged RTV's. I dont know how many times an extra 10 or 15hp would of gotten me through that mud hole or kept those tires turning.

Sounds interesting, will be a great project to follow. The extra horsepower will be nice and the turbo should sound great as well. Take plenty of pictures and keep us posted.

Yes, pictures please

historically, turbocharging motors that weren't designed for such extreme temperatures / RPMs decreases the engine lifespan.

it's a utility vehicle - not a rocket -- if you want a rocket, get a sport quad.

More like underpowered vehicle, I'm not wanting to crank out 100hp (i wish though) and i do agree with compromising the engines durability. I'm not wanting to build a high performance motor, just give it a boost. I figured 5-7lbs of boost max should be all I need. Im only o-ringing and porting the head to help flow the added boost better and to make sure everything stays where its supposed to. I'm trying to do it for less than $1000. So far i'm up to $268, thats the new turbo, used intercooler, and new fan. The little things like wiring, tubing etc will add up pretty quick.

if you want a place to start, Kubota probably builds a turbo version of that engine. Check out the Kubota-Engine website where they market engines for industrial use, find one with your block number and you can get an idea of the boost the Kubota uses themselves.

cant wait to see it. sounds awesome.

I'm sure interested in watching the progess. It is a very interesting project. In 76 I turbocharged a 65 Mustang with a universal kit from Accel. It sure makes a difference.

 

[joeshmoe_44883]

Wow thats before my time but turbocharged cars weren't really that popular back then. Turbo technology has really jumped leaps and bounds since then. My goal with this is making a professional looking, factory look. I want it to look like it was made that way. Definitely take my time to make it look right and hopefully perform great.

 

[Old Coot]

Your right. When I told the speed shop where I was going to put the turbo, he said there wasn't enough room in the Mustang. Just had to come up with some different exhaust manifolds. Not only turbos have come a long way but the rest of the engines to. Varaible valve timing is one of my favorites.

 

[joeshmoe_44883]

My favorite are diesels, but modern engines are an engineering masterpiece for sure. But I wish they made engines as simple as they used to easy to work on and alot less stuff to go wrong. Judging the picture you posted you did a very fine job of installing it, had to of been quite the attention getter!

I would be interested if anyone offers a similar kit for the JD Gator with the Yanmar 24.8 hp diesel (850d). I have been happy overall with my machine's power and really do not want to go any faster. I would like a bit more mid range power when pulling a heavy trailer, etc. uphill or plowing snow. There have been times I have had to go into the lower range which is much slower because the engine was laboring in H. I would like to spend more of these times in H.

Well to give everyone a quick update, the turbo, intercooler, intercooler fan, and my snorkel have all come in. The turbo is off to a machine shop getting flanges made, as well as a little bit of porting of the exhaust housing to smooth the flow out. All thats left is a bit of pipe work, plumbing the lubrication system, and the gauges and i'll be all set. I'm making a custom gauge pod that will hold the turbo boost and EGT gauge, should look neat along with "it came from the factory that way" look. I'm in N.C. at the moment but once i return to ohio I'll begin work and get some pictures posted up asap.

Where does one go to find cheap small turbos? I would like to put one on a 172 diesel 2200 rpm max, but don't know diddlie about turbos!

Becareful about dunking your turbo if you like water holes and mud. They don't like the thermal shock of being dunked.

 

[joeshmoe_44883]

I got my turbo off ebay, I got lucky and found the exact turbo i was looking for. Turbocharging a diesel is alot easier to do compared to gas powered engines, but there's still alot of math you have to do before you buy your tubo. A mismatched turbo/engine combination will produce worse results than the motor was stock. If you want to learn about turbocharging, visit your local barnes and noble bookstore. Look in the transportion section and you'll be sure to find books on supercharging and turbocharging engines.

Here is a video on youtube of a guy who done this..

neat stuff

Joeshmoe. I was just interested in an update on your turbo project. How did everything end up? Are you pleased with your new toy?

I have 2 RTV 900s and am considering a lift and turbo kit for both, and possibly a track kit for one. There is a non-intercooled kit from swag for $2650 and they recommend dealer installation because of injector pump issues. Plus, multiply the kit cost times two and the dealer install times two and I could probably just add a third UTV to my lineup for a few more dollars!!!

I am mechanically inclined and have friends who build racecars for a living, and like you would prefer to have an intercooled version and some cool gauges. I think that the fabrication and installation of this project would be fairly simple. Its just a matter of chosing the right turbo and some minor tuning, but feel free to correct me if I'm wrong.

If you have any pics, comments, or afterthoughts I would love to get some input from someone with hands-on experience. Oh yeah, what kind of tracks and how do you like them? Thanks!!!

I also would like to hear how joshmoe did on his turbo install.Does anyone know where the turbo oil return line terminates on the engine? My friend said that one company runs silicone line from below the turbo around to the other side of the motor and attaches it to the valve cover for oil return.I`d also like to know how to do the pump adjustment for peak torque and hp- anyone?

Hello everyone, its been awhile since I last updated. Had a big oil spill in Cygnet, Ohio that I had to respond to so I havent done anything to the ol' bota. One new update is after some searching I found out Kubota does make a turbocharged version of the 1105 engine, which is in the 1100's, that makes 32hp compared to our 24hp. Which gives me hope that there is more power to be had than what I was hoping for. Now I want to pust 40hp . Soon as I get some time i'm gonna search where the nearest place is that deals with Kubota engines. I want to take a look at all the service an parts books and see if i can use some factory parts from the turbocharged version that will bolt right onto my motor, making the install easier and quicker.
They also make a version that is governed to 3600rpm's vs 3000 in the 1100's. Will have to do some research on why we cant install the 3600rpm govenor to get a lil more top end, but not sure what it would do to a hydrostatic transmission. The higher speed might cause the oil to cavitate, spelling disaster. Lots of research to do and a few more parts to gather. This project is taking longer than expected, but once I get started with the install it should go together quickly. As promised I'll take pics as I go along. So far nothing interesting has been happening. Besides its always easier to work in the shop when its warm an sunny out compared to the 20 degree weather we had.
